为研究天线选择下准正交空时分组码(QSTBC)系统信道容量的改善程度,以TBH码为例推导出平均信噪比表达式,并以此作为天线选择的准则,计算出QSTBC系统容量.仿真结果表明:无论采用何种QSTBC码,天线选择下的准正交系统的信道容量都将明显增加.
為研究天線選擇下準正交空時分組碼(QSTBC)繫統信道容量的改善程度,以TBH碼為例推導齣平均信譟比錶達式,併以此作為天線選擇的準則,計算齣QSTBC繫統容量.倣真結果錶明:無論採用何種QSTBC碼,天線選擇下的準正交繫統的信道容量都將明顯增加.

To investigate the improvement degree of channel capacity of quasi-orthogonal space-time block code (QSTBC) system based on antenna selection, TBH code was selected and its expression of average signal-to-noise ratio was deduced, which was used as the criteria for antennas selection to calculate the channel capacity of QSTBC system. Simulation results show that the channel capacity of QSTBC system with antennas selection is improved obviously.
